How many solutions does this system of linear equations have? Explain.
1= 2
=1+3 2
Answer: There are no real solutions.
Step-by-step explanation:
We have the equation:
x = y^2
y = x + 3/2
To solve this, we can start by noticing that x is already isolated in the first equation, then we can replace it in the second equation to get:
y = y^2 + 3/2
And now we can rewrite this as:
y^2 - y + 3/2 = 0
This is a quadratic equation, and the solutions can be calculated with Bhaskara's equation, the solutions are:
[tex]y = \frac{-(-1) +- \sqrt{(-1)^2 - 4*3/2*1} }{2*1} = \frac{1 + \sqrt{-5} }{2}[/tex]
We have a negative number inside the square root, this means that the solutions are complex numbers.
Then we can conclude that the system of equations has no real solutions.

A metric ton is 1,000 kg, and a British ton is 2,000 lb. Which has the greater weight?
By how much?
Answer:
A metric ton weights more because a kg is equal to about 2.204 lbs.
1000 x 2.204 = 2204 lbs > 2000 lbs
Step-by-step explanation:
Hope this helps! Have a nice day!
The greater weight is 1000 metric ton and it is greater than a British ton by 205 lb
A metric ton = 1000 kg
British ton = 2000 lb
Converting both measures to the same unit :
1 kg = 2.205 lbA metric ton to pounds = (1000 × 2.205) = 2205 lb
Therefore,
A metric ton = 2205 lb A British ton = 2000 lbComparing the weight :
2205 > 200020002205 - 2000 = 205 lbTherefore, the greater weight is 1000 metric ton and it is greater than a British ton by 205 lb

gold
Answer:
3 gold
3 silver
18 bronze
Step-by-step explanation:
Look at the ratio. 1:1:6. Add the numbers together and you get 8 right?
8 × 3 = 24
Now that you know how much to multiply each part of the ratio by, (3, if you didn't get that.) now you multiply.
1 × 3 = 3 Gold

The base of a house has area 110 m². One night 12 mm of rain falls on the roof. All of the water goes into a tank which has base diameter 4 m.
a Find the volume of water which fell on the roof.
b. How many KL of water entered the tank?
c. By how much did the water level in the tank rise?
Answer:
a. 1.32 m³
b. 1.32 kL
c. 105.04 m
Step-by-step explanation:
Area of roof = 110 m²
Rain fall = 12mm = (12/1000)m = 0.012 m
(a) Volume of water that fell on roof = Area of roof × Rain depth
= 110 × 0.012
= 1.32 m³
(b) 1 m³ = 1 kL
∴ 1.32 m³ = 1.32 kL
(c) Radius of tank = (4/2) = 2 m
Volume of tank = Base area × Height
= πr²h
= π × (2)² × h
= 4πh
The volume added to the tank must be equal to the volume which falls on roof.
i.e. Volume of tank = Volume of water that fell on roof
or, 4πh = 1.32
or, h = 1.32 / (4π)
∴ h = 0.10504 m = (0.10504/100)cm = 10.504 cm
∴ The water level rises by about 10.504 cm.

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 8.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 250 engines and the mean pressure was 8.1 pounds/square inch. Assume the variance is known to be 1.00. A level of significance of 0.01 will be used. Make a decision to reject or fail to reject the null hypothesis. Make a decision
Answer:
The calculated value z= 0.0063 does not fall in the critical region so we fail to reject the null hypothesis. And accept that the valve does not perform above the specifications.
Step-by-step explanation:
Given that
Population mean= μ = 8.0
Sample mean= x`= 8.1
Sample size= n= 250
Sample standard deviation= s= 1.00
Significance level= ∝ =0.01
The null hypothesis and alternate hypothesis are
H0: μ < 8.0
Ha: μ ≥ 8.0 One tailed test
The claim is that the valve perform above the specifications
The critical value at 0.01 significance level for one tailed test is z > ±2.33
The test statistic z is used
z= x`- μ/ σ/√n
Z= 8.1-8.0/ 1/√250
z= 0.1/1/15.811
z= 0.0063
The calculated value z= 0.0063 does not fall in the critical region so we fail to reject the null hypothesis.
Daisy works at an ice-cream parlor. She is paid $10 per hour for the first 8 hours she works in a day. For every extra hour she works, she
is paid 1.5 times her hourly wage. If Daisy works for x hours in a day, and is greater than 8, the expression giving her net earnings for
the day is
v. if Daisy works 13 hours, she will be paid ($1557
Answer:
The expression giving her net earnings for a day with more than 8 hours worked is X = 80 + 15H, where H means "extra hours worked".
Step-by-step explanation:
Given that Daisy works at an ice-cream parlor earning $10 per hour for the first 8 hours she works in a day, and 1.5 times her hourly wage for every extra hour she works, in order to know how much can she make in a day working more than 8 hours the following equation has to be made:
X = (8 x 10) + (H x (1.5 x 10))
X = 80 + 15H
Therefore, if Daisy works 13 hours, the equation works as follows:
X = 80 + 15x13
X = 80 + 195
X = 275
finding the slope (simplest form)
Answer:
m=3, y = 3x - 2
Step-by-step explanation:
slope = rise / run
slope = 6/2
slope = 3
Answer:
The slope is 3.
Step-by-step explanation:
Slope is equal to rise over run. Let’s take a look at the points given to us on the graph.
To go from the leftmost point to the rightmost point, we rise (go up) 6 units, and then we run over (go right) 2 units. So we have:
Slope = Rise/run = 6/2
Now 6/2 is equal to 3, and that’s the slope.
Huong is organizing paperback and hardback books for her club’s used book sale. The number of paperbacks is 12 less than three times the number of hardbacks. Huong had 162 paperbacks. How many hardback books were there?
Answer:
There were 58 hardback books there.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of paperback books.
y is the number of hardback books.
The number of paperbacks is 12 less than three times the number of hardbacks.
This means that:
[tex]x = 3y - 12[/tex]
Huong had 162 paperbacks.
This means that [tex]x = 162[/tex]
How many hardback books were there?
We want to find y.
So, using the value of x, and the first equation, we have that:
[tex]x = 3y - 12[/tex]
[tex]3y = x + 12[/tex]
[tex]3y = 162 + 12[/tex]
[tex]3y = 174[/tex]
[tex]y = \frac{174}{3}[/tex]
[tex]y = 58[/tex]
There were 58 hardback books there.

Sam created the figure below using a rectangle and two congruent triangles. The side lengths of the
rectangle and the base and height of the triangles are shown
What is the area of the shaded region in square inches?
a.112.5in
b.105in
c.135in
d.120in
Answer:
b. 105 in
Step-by-step explanation:
Area of a triangle = ½ bh [base × height].
Area of a rectangle = lw [length × width].
The shaded region is taken up by the two triangles which means that you subtract the area of the rectangle from the two triangles.
Assuming that the two triangles are congruent [same shape and size], the area of the two triangles are really just the base times the height because ½bh + ½bh = bh.
So 3 × 5 = 15 in.
The area of the rectangle shown is its length times it's width which is 15 × 8 = 120in.
Now just subtract the area of the rectangle from the area of the triangles that are taking up the area:
Therefore,
Area of the rectangle – Area of the triangles = shaded area
120in – 15in = 105in = shaded area.

Answer:
10
Step-by-step explanation:
Let us find the exact number of donors of gold and bronze respectively given there are 40 in total.
Gold: 45% of 40 = 45/100 *40 = 18 donors
Bronze: 20% of 40 = 20/100 *40 = 8 donors
18 donors - 8 donors = 10 more donors

m = (y2 -y1)/(x2 -x1)
Find:
a) the slope of the line through these points
b) the y-intercept of the line through these points
c) the equation of the line through these points
Solution:
a) Using the given formula, the slope is ...
m = (7 -4)/(2 -1) = 3/1 = 3 . . . the slope of the line
__
b) The y-intercept can be found from* ...
b = y1 -m·x1
b = 4 -3·1 = 1 . . . the y-intercept
__
c) The equation in slope-intercept form is ...
y = mx +b
y = 3x +1
_____
* This equation for the y-intercept is not one you see often. It can be derived from the point-slope form of the equation of a line:
y -y1 = m(x -x1)
y = mx -m·x1 + y1 = mx +b . . . . eliminate parentheses, add y1
b = y1 -m·x1 . . . . . . . . solve for b
